Description
Poster session
Ground-based detectors are strongly limited at low frequencies [5 - 30 Hz]. Unlocking these frequencies requires the development of new technologies, and will allow terrestrial detection of new, and more distant sources. Additionally, source localisation and forewarning will provide opportunities for spectacular multi-messenger observations.
We propose a new kind of inertial isolation system...
Abstract
Einstein Telescope is a proposed third-generation gravitational wave detector
which is expected to have an increased broadband sensitivity by a factor of 10
with respect to advanced detectors while also extending the low frequency sen-
sitivity of ground based gravitational wave interferometers below 10 Hz. Grav-
itational wave observations using a network of detectors permits a...
We present the estimates of the impacts related to the construction and operating phases of the Einstein Telescope (ET) research facility. Precisely, we provide estimates of the total output, value added and employment impacts of ET as well as some preliminary estimates of social impact.
A tool for time series analysis based on adaptive methodologies such as Empirical Mode Decomposition (EMD) and its time varying version tvf-EMD, has been developed and applied to characterise seismometer data monitoring Virgo North End Building (NEB) recording during four different acoustic noise injections. The tool quantifies the trend/baseline wandering eventually present in the data and...
The selection of sites for underground gravitational wave detectors based on spectral and cumulative characterization of the low frequency seismic noise. The evaluation of the collected long term seismological data in the Mátra Gravitational and Geophysical Laboratory revealed several drawbacks of the previously established characteristics. Here we demonstrate the problematic aspects of the...
Sardinia ET project involves the realization of an underground infrastructure with two possible geometrical arrays which develop along approximately 30 km of tunnel. The site is near Sos Enattos mine (North-eastern Sardinia), where currently physics laboratories are already active.
The positioning and orientation of the infrastructure and the relative tunnel tracks were chosen taking into...
There are no other large instruments that are limited so much by availability of materials like the Earth based GW detectors. Thermal noise and optical absorption in mirrors and their suspensions are a strong limiting factor for future upgrades of existig detectors and also in new projects like Einstein Telescope. A new group at the Insitut Lumière Matière, Lyon, has been formed with the aim...
Wave-front aberrations in the core optics of interferometric gravitational waves detectors can represent a strong limitation to their operation and sensitivity. These aberrations are due to intrinsic defects in the optics (surface figure errors and refraction index inhomogeneity) and to the rise of thermal effects, i.e. optical power absorption in the substrate and coatings of the test masses...
